GAS-MANTLE.

Patented Nov. 5, 19o).

Application filed August 10.1901. Serial No. 387.985.

To all whom it may concern: I

Be it known that I, PAUL R. Frxcn. a citizen of the United States, residing in Des Moines, county of Folk,

Improvement in Gas-Mantles, of which the is a specification.

The object. of my invention is to provide a-mantle for inverted gas lamps which will be simple, strong J. durable and inexpensive in construction andwhich will be adapted to produce a greater,degreepflight from a small supply of heat than any of the mantles following A iurth'er object to provide a mantle wherein the.

doing away with the central opening and tying cord usually employed in forming the base of inverted mantles. My invention consists; of certain details 01 was-truction hereinafter setforth, pointed out in my claims and illustrated in the accompanying drawings in which Figure I showsan inverted plan view of my device; Fig. II shows a perspective view of my device; and, Fig. III shows a second perspective'view of the same.

Referring to the accompanying drawings the reference numeral 10 is used to indicate the mantle holder provided With its supporting lugs I1 and the numeral the mantle-proper which is commonly called the web. I I

The numeral 13 indicates a longitudinal seam 10- cated on one side of the itch said seam branching into point near the hemi-spherical base of the mantle. Directly opposite to the seam 13 and located longitudinally in the mantle 12 is a second seam 16, exactly similar in every respect to the seam 13, and branching near'the base of the mantle into two scams 1? and 18. The extremity of the base of the mantle is absolutely seamless and the object of the longitudinal seams 13 and 1G and their respective branches is to produce the curved base in the bag so that when the mantle is properly treated w ith the necessary chemicals and secured to -the holder 10, it will be provided with' an even,'

ner as shown at 19. It isobvious 'that -by this construction-an even and symmetrical mantle simple, durable and inexpensive in construction will be produced. Theseams 13 and 16 and their respective I I a v branches are produced n the bag by a. knitting process thus obviously causingthem to be small and neat and not presenting a thickness much greater than the regular and symmetrically; curved base void of seams at its extremity. The. mantle 12 is secured to the holder 10 in the usual man bag itself and causing very little it any added *ob'struction to the fiow of light.

Different styles of'this class of mantles in which the side seams are employed may be produced Without changing is to produce the seamless base extremity and thus provide an evenness of the mantle bag with no added obstruction to the flow of light at any particular spot.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is: L

l. gas mantle embodying a cylindrical vel) having a Henri-spherical base formed evenly and symmetrically. :1

pair of oppositely disposed longitudinal seams extending- \ergent branches extending, from the' lower end of each seam to extend on the outer portions 'of the base extremity.

L. A gas mantle embodying a-cyiindrical web having a liemi-spllei'iczll base, said web being divided in its body into two arts by a pair of straight seams and'adjacent the extremity of the hemispherical base having its line of ill vision extending in curved paths so as to'be on the outer [nil-Hells of the'extrernity of the hemispherical l ase.
